What is the usual crocodilian temperament?
As a rule, you should exercise caution around any of these reptiles. They are not domestic, and a bite can inflict serious injury. Generally the crocodile is the most aggressive, followed by the caiman, and then the alligator and gharial. There may, however, be notable exceptions. For example, the rare American Crocodile, ‘Crocodylus acutus’, is reported to be temperamentally closer to the American Alligator than its nearer relatives.
